Abstract: A “one-step” method of forming diffused noble metal-aluminide coatings with or without minor incorporations of Si, Cr, Mn, Hf, La, and Y, is disclosed. With the inventive method, two or more powdered metals or metal alloys are applied and diffused into the metal substrate together, using a sequential multi-stage heating process. This method contrasts with the prior art technology where metals were applied and diffused into the substrate separately.

Abstract: Abradable wall structures for high temperature applications, such as in turbine housings and the like. The wall structures comprise a superalloy metal base plate supporting a superalloy metallic cellular structure, the cells of which are filled to a substantial extent with at least one ceramic core material providing high heat resistance, oxygen barrier and low thermal expansion properties. The invention involves the application of a porous or pore-forming surface composition to provide a corrosion-resistant, erosion-resistant abradable outer surface layer, the softness or porosity of which can be tailored to improve the abradability of the wall structure, while imparting oxidation-, corrosion- and erosion-resistance to the structure. The surface layer composition may comprise metal superalloy, ceramic or cermet base compositions containing fugitive or retained inert filler materials.

Abstract: Erosion resistance is imparted to a metallic substrate without an attendant loss of fatigue life in the substrate in one embodiment by applying to the substrate a first ductile layer comprising a metal from Group VI to Group VIII elements as well as the noble metal group of elements, and a second hard erosion-resistant layer applied on the first layer comprising a boride, carbide, nitride or oxide of a metal selected from Group III to Group VI elements, the first layer capable of retaining substrate integrity and preventing diffusion of material from the second layer into the substrate. Another embodiment defines another layer of a substantially pure metal from Group III to Group VI between the first and second layers. Still another embodiment defines that in the second layer the content of either the carbide, nitride, boride or oxide is graded, i.e. the concentration of either the carbide, nitride, boride or oxide is greatest (higher) toward the top surface of the second layer, and decreases toward the bonding surface between the second and first layer.

Abstract: Dry film lubricant coatings are provided by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate. The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent—although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.
